Results reveal △G~(β_1 →α')> 0 within the trans-formation temperature range 60--750 K. Therefore, the bainitic transformation cannot beinitiated by the β_1→α' shearing mechanism. On the other hand, the driving force △G~(β_1→β_2+α)to produce 5% of the α becomes negative only when the composition of the α satisfiesx_(Al)~α≤0.204 at 700 K or x_(Al)~α=0.209 at 750 K. So the bainitic transformation can only proceedby β_1→β_2+α diffusional reaction with diffrent diffuson amount at different temperatures.
